[Dnsmasq-discuss] pxe-service line for UEFI system?

[Michal Zatloukal]

Hi.
I'm putting together a "booting section" fo my config, where I want to
provide various boot images, according to the machine architecture
provided by the client. As I understand the pxe-service functionality,
there are 2 ways to to netboot:
- either provide bootfile-name (67), which the client downloads
immediately and executes, or
- provide pxe menu, (prompt, items), within option 43, client makes a
selection,  DHCP provides filename for the selected item, and from
there it's the same as the above.

The config (attached below [1]) works fine for PC-BIOS, but I just
can't get dnsmasq to provide any PXE menu items to X86-64_EFI clients.
Tried the CSA keyword (X86-64_EFI), integer (7), removed the skipmenu
tag filter, commented out all pxe options specific to other
architectures, nada. For the UEFI client (using vmware VM), the
provided option 43 only contains the prompt suboption, and end
character (the VM doesn't display anything and just goes back to boot
menu, but that's down to their PXE ROM, I assume). Double-checked CSA
provided by the client, it is indeed 7 (+
PXEClient:Arch:00007:UNDI:003016 in VendorClass).  What am I missing?

The dnsmasq instance is a full DHCP server, not just proxy. I can
private-message the full config if you need it. I'm on ubuntu-provided
version 2.80-1ubuntu2.

Cheers,
MZ
